The Manchester rain lashed down on Louis van Gaal and in such a corrosive atmosphere it could have turned acidic.

United fans' mutiny was as disaffected as the Bounty crew's. After the initial booing at Old Trafford subsided, it became louder as Van Gaal edged nearer to the tunnel. Once he disappeared, it stopped, and the booing was replaced by applause. For the players.

This happened twice on Saturday. Once at half-time and once at full-time. The only difference was the cacophony of boos was louder after United suffered a sixth Premier League defeat of the season.

It was not just restricted to booing. 'Van Gaal out' was previously synonymous with Twitter speak, a hashtag that trended. Not anymore. Numerous supporters uttered those three words as the Dutchman skulked down the touchline. One young fan sat in the mild mannered south stand made the w****r gesture at the United manager.

So how is Van Gaal still clinging on to his job? Here the M.E.N's Samuel Luckhurst, answers the key questions.
